ABSTRACT:
A method of determining availability of a connection between a wireless local area network and a home network of a mobile user device prior to initiating connection or authentication comprises selecting a network device; and sending a probe signaling message comprising a user device to the selected network device. The network device uses this home identifier data to formulate a signaling message that it sends towards the appropriate home network to contract a home authentication server. An indication to the user device of the result of the attempt is returned.
